U-duality of Born-Infeld Theory
Gysbert Zwart
String theory compactified on a three-torus possesses an SL(5,Z) U-duality group. We investigate the realisation of this symmetry on the Born-Infeld theory on a three-brane, and di…
U-Duality in Supersymmetric Born-Infeld Theory
Gysbert Zwart
The Born-Infeld theory of a toroidal D3-brane has an SL(5,Z) U-duality symmetry. We investigate how this symmetry is reflected in the supersymmetry algebra. We propose an action of…
U-Duality Invariance of the Four-dimensional Born-Infeld Theory
Christiaan Hofman, Erik Verlinde, Gysbert Zwart
We calculate the Hamiltonian of a compactified D4-brane, with general fluxes and moduli, and find the BPS-mass. The results are invariant under the complete U-duality SO(5,5,Z).
Matrix Theory on Non-Orientable Surfaces
Gysbert Zwart
We construct the Matrix theory descriptions of M-theory on the Mobius strip and the Klein bottle. In a limit, these provide the matrix string theories for the CHL string and an orb…
Four-dimensional N=1 Z_N X Z_M Orientifolds
Gysbert Zwart
We calculate the tadpole equations and their solutions for a class of four-dimensional orientifolds with orbifold group Z_N X Z_M, and we present the massless bosonic spectra of th…
